Question

विस्तार सूत्र वापरून गुणाकार लिहा- (a + 6) (a - 6)

Answer 1

विस्तार सूत्र वापरून गुणाकार लिहा- (a + 6) (a - 6)

We are aware of this identity,

(a + b) (a - b) = a^2 - b^2

Similarly,

In your question,

$\tt{(a + 6) (a - 6) = {a}^{2} - 6 {}}^{2}$

Simplifying it further,

we get :

$\tt{ = {a}^{2} - 36}$

Thus,

a^2 - 36 is the answer.

Answer 2

ITS AN IDENTITY........

(x) ² - (y) ²= (x+y) (x-y)

So......

(a+6)(a-6)=a²-6²=a²-36____Answer.....
